The 2018 Ontario Natural Building Coalition's annual

Natural Building Conference & AGM 2018

will take place on April 7 and 8, 2018, at Camp Kawartha, near Lakefield.

This year's theme: "Building Within Reach"

This year we will continue to include community growth and personal health in our annual natural building conference. To that end, we are planning two parallel streams throughout the weekend: A technical stream focusing on our professional member’s strengths and interests - on natural building with an emphasis on pre-fabrication and modular design using natural materials, as well as on-going carbon accounting and regulatory discussions. The community stream will focus on personal and community health, reconciliation between First Nations and settler communities and affordable/accessible sustainable housing.

Some of the presentations planned for this year's conference include:

Lisa Ker of Salus Ottawa, on Affordable Housing

David McAuley, Architect, on Sustainable Communities with Multi-family Dwellings

Marianne Griffith and Chief Henry Myeengun, on Reconciliation between First Nations & Settler communities

Bobby Ilg and Kris Bailey on Light Straw Clay Panels

Chris Magwood and Shane MacInnes of Endeavour, on Panelized Construction Zero House and Carbon Accounting

Chris Vander Hout of Evolve Builders, on moBEE pre-fabricated straw bale buildings 

Shane MacInnes of Greening Homes, on How to Define Sustainable Building and Track Sustainable Construction Goals

Our two day conference also includes a Saturday evening slide show of participants and members buildings and building designs, a musical jam (bring your instruments), great food, and plenty of opportunities for socializing and networking. This is a fabulous event, not to be missed!

The Ontario Natural Building Coalition's Annual Ontario Natural Homes Tour

Natural building construction uses locally obtained and renewable materials, to produce homes and buildings that are visually unique and healthy to live in, while striving to keep energy consumption 

and its’ associated emissions as low as possible. 

As a way of promoting natural building, the Ontario Natural Building Coalition coordinates an 

annual Natural Homes Tour, in the early autumn each year. For the tour, dozens of natural homes and buildings across Ontario open their doors for participants to see examples of straw bale, rammed earth, cob, timber frame, off grid, passive solar, and many other natural building methods and alternative technologies. Check back in August for our 2018 date.


Visit our Natural Building Gallery to see houses built out of straw, wood & earth!

A Natural Home Tours Thank You

Over the years, many homes and buildings have participated in our Natural Building Annual tour.

Many of the homes that have been featured were models of innovation and energy efficiency and featured living roofs, natural clay wall finishes, rainwater catchment systems, grey water systems, composting toilets, while others incorporated solar and wind electrical systems, high efficiency wood burning appliances, solar domestic hot water systems, as well as a variety of other interesting green technologies.

The Ontario Natural Building Coalition would like to thank all the volunteer homeowners who have over the years graciously opened their doors and welcomed tour-goers. The annual tour would not be possible without them!
